Trust. It depends on the project and whos running it
Fund: Yes on occassion.
Ive put money toward Planetary annihilation, Shadowrun returns, Eternity, Torment, Nekro, and Wasteland 2 to name a few. I consider that money gone completely and I understand that I may never get a product for the money I put down. Im not an investor, if I was I would actually invest in a single company or project that I thought was worthwhile. That said, I have gotten some great games from Kickstarter. Shadowrun was my favorite RPG of last year and Im pretty happy with how Nekro turned out as well. PA Ive got some issues with but its not a bad game by any means. Then there's Wasteland 2 which Ive got some big concerns with their thematic approaches even though the game is pretty solid.
As you can see Kickstarter has been pretty good to me so far because Im pretty picky with the projects I fund. If a dev doesnt have something concrete to show me then I wont give them any money. Today I need a demo or something representative of the game to feel confident enough to put money down on it. That wasnt the case at first but thats how my kickstarter funding philosophy has developed over time.
In the case of star citizen they did not do an actual kickstarter campaign as far as Im aware. It's a private crowd funded project. However that project has blown up because the development team behind it has done everything right. They've been transparent with backers, theyve done regular updates and gameplay demo's, Im pretty sure they even have a road map to give a rough idea of what theyre working on when and when they'll add or adjust features. If you want to check out some of star citizen I recommend looking up a channel on youtube by the name of Luetin09. Hes done several videos on the game which are pretty informative.
The thing about kickstarter is you have to inform yourself if you want to feel like your money has been well spent and you may have to admit that the project you funded may never get made. You can get projects like shadowrun returns that are everything you wanted out of it and more. Then again you can get projects like Takedown:Red sabre that are complete garbage on release (although that ones gotten better but still has a ton of issues).
